Use the law of cosines to write an expression equivalent to b

andrezito [222]

Given:

A triangle ABC.

The given expression for b is:

$b=\sqrt{m+n-pq}$

To find:

The expression that is equivalent to b.

Solution:

According to the Law of Cosines,

$b^2=a^2+c^2-2ac\cos B$

It can be written as:

$b=\sqrt{a^2+c^2-2ac\cos B}$ ...(i)

We have,

$b=\sqrt{m+n-pq}$ ...(ii)

On comparing (i) and (ii), we get

$m=a^2$

$n=c^2$

$p=2ac$

$q=\cos B$

Therefore, the required values are $m=a^2,n=c^2,p=2ac,q=\cos B$ .

lisov135 [29]

Answer:

2232.48 meters

Step-by-step explanation:

From the diagram:

Radius of semicircle = 74

Length of straightway on each side = 1000

The length of school track :

Straightway on each side = 2 * 1000 m = 2000m

Length of semicircle = πr/2

Length of both semicircle = 2 * 3.142 * 74 /2 = 232.47785

Total Length = ( 2000 + 232.47785) = 2232.48 meters
